All I can say is WOW! As many other customers, we purchased these for a 15+ year old dog who just couldn't get up our wood steps easily. These are not only attractive, they helped her get up the steps. We bought the dark brown and the only down size is it easily collects our dogs long hair (to be expected though). They are very easy to vacuum or even take a stiff brush across the tread to collect the hair. We are very pleased with these.
